Subject: [PATCH 1/2 V2] staging: dgnc: ch->ch_bd is already assigned to bd variable
Date: Tue, 14 Mar 2017 11:05:32 +0900	[thread overview]
Message-ID: <20170314020503.GA22933@SEL-JYOUN-D1> (raw)

The bd variables in functions are already assigned from
ch->ch_bd but it is not used in those functions except checking NULL.

The ch->ch_bd could be replaced with bd variable.

Signed-off-by: Daeseok Youn <daeseok.youn@gmail.com>

V2: Patches in previous series are splited but it could be merged into one.
There are lines to replace ch->ch_bd with bd variable.
